Weight loss happens when the body uses more calories than it takes in.
General health information from federal public-domain sources — not medical advice, diagnosis, or treatment.
That was one real, public federal answer — and it's free. Receptivity scoring and the audience-safety verdict on every cue come with a free key.
With a free key
The facts are public and free — that's the safety model. The free key unlocks the live cue loop — every cue scored for receptivity and checked safe for its audience. Clinical arc sequencing switches on with a paid stream.

One fact is the demo. The arc is the product.
The call above returns one fact. On a paid stream, Signal sequences the whole federal library into a per-episode arc — each message placed by day and phase, checked safe for the patient, and timed to when they are most likely to act. Here is the opening phase of a real clinical arc.

Why a key, not a pipe
“We’ll just use Twilio.”
Twilio sends. Signal decides what to send, whether it is safe for this person, and what comes next.
“The content is free.”
It is — we source from the same CDC and NIH pages. You pay for the sequencing, the audience-safety verdict, and not maintaining freshness and linting yourself.
